Who it is for
What we do and what we leave to you
We list donor sites, take your order and publish one article with one clean link to your page. That is the product.
Choosing a host whose readers care about your subject, and an anchor that fits its sentence, stays with you. So does the judgement about risk. Placements are permanent dofollow, and Google's link spam policies cover paid links that pass ranking signals, so a handful of well-matched placements beats a bulk order of anything.
Read the host article scorecard before your first order, then look at where the link goes inside the article.
